The Worcester Bosch 87183102110 is a protection switch used in Greensource air/water heat pumps. It monitors a safety condition within the appliance and interrupts operation when that condition is exceeded, protecting the compressor and refrigerant circuit from damage.

Signs this part needs replacing

  • Heat pump locks out or shuts down shortly after start-up
  • Repeated fault codes relating to pressure or safety cut-out
  • Compressor fails to run despite a call for heat
  • Intermittent operation that clears after a reset but returns

Before you order

  • Confirm your appliance model matches one of the fitments listed above
  • Check the part number on the existing switch against 87183102110
